• Prairie and forest vegetation of the Armand Bayou Nature Center, Harris County, Texas ﻿

(1990)
The prairie and bordering woodlands of the Armand Bayou Nature Center, Harris County, Texas were sampled as an example of Texas Upper Coastal Prairie. The prairie is homogeneous and species-rich but shows very low dominance. ...
• Prandtl-Meyer expansion of an ionizing monatomic gas ﻿

(1962)
The Prandtl-Meyer flow of a pure, monatomic gas, including the effects of ionization and recombination, has been numerically calculated. Expressions describing the thermodynamic state of the gas mixture were obtained from ...
• Pre-Tertiary stratigraphy, magmatism, and structural history of the Central Jackson Mountains, Humboldt County, Nevada ﻿

(1996)
The Jackson Mountains (JM) are part of the early Mesozoic continental arc in northwest Nevada, which was constructed upon previously accreted Paleozoic basement. The stratigraphy of the Paleozoic basement exposed in the ...
• Precise determination of the 2P radiative atomic lifetime of lithium using photoassociative spectroscopy ﻿

(1995)
Spectroscopy of the high-lying vibrational levels of the $1\sp3\Sigma\sbsp{g}{+}$ and $1\sp1\Sigma\sbsp{u}{+}$ states of both $\rm\sp6Li\sb2$ and $\rm\sp7Li\sb2$ has been accomplished via photoassociation of ultracold ...
• Preconditioned iterative methods for inhomogeneous acoustic scattering applications ﻿

(2010)
This thesis develops and analyzes efficient iterative methods for solving discretizations of the Lippmann--Schwinger integral equation for inhomogeneous acoustic scattering. Analysis and numerical illustrations of the ...
• Preconditioner schemes for elliptic saddle-point matrices based upon Jacobi multi-band polynomial matrices ﻿

(1995)
Simulation of flow in porous media requires the numerical approximation of elliptic partial differential equations. Mixed finite element methods are frequently employed, because of local mass conservation and accurate ...
• Preconditioning the integral formulation of the Helmholtz equation via deflation ﻿

(2006)
In this thesis we propose methods for preconditioning Krylov subspace methods for solving the integral equation formulation of the Helmholtz partial differential equation for modeling scattered waves. An advantage of using ...

(1967)
• Predicting postinterview impressions from preinterview information: An examination of behavioral mediators ﻿

(1994)
Consistent with previous findings, interviewers' postinterview evaluations of applicants for correction officer positions were positively related to preinterview information on the applicants. The interviewer's conduct of ...
• Predicting Professional and Technical Performance among Medical Students: Personality, Cognitive Ability, and the Mediating Role of Knowledge ﻿

(2012)
The distinction between technical and contextual performance is widely recognized in the Industrial/Organization Psychology literature (Sackett & Lievens, 2008). Less well-understood are the causal antecedents of performance ...
• Predicting protein-protein interactions from primary structure ﻿

(2002)
One of the key challenges in the post-genomic era is to understand protein-protein interactions on a large scale. Given the primary structures of proteins and ligands, along with other information, how well can we ...
• PREDICTING THE USABILITY OF ALPHANUMERIC DISPLAYS ﻿

(1984)
A review of the literature on alphanumeric displays, especially computer-generated displays, suggests that four basic characteristics of display formats affect how well users can extract information from the displays: (1) ...
• Prediction of fatigue life in relation to surface finish parameters ﻿

(1989)
One can safely claim that not one single surface roughness parameter, in terms of completely characterizing a surface, can be exhaustive. This study is both an experimental and theoretical study of characterizing surface ...
• Prediction of magnetospheric parameters using artificial neural networks ﻿

(1994)
Artificial neural network models have been developed that provide the magnetospheric parameters Dst, polar cap potential and the midnight equatorward boundary of diffuse aurora. Layered feedforward neural networks have ...

(1966)
• Prediction of the thermodynamic properties of associating polyatomic fluids ﻿

(1995)
Thermodynamic properties of associating polyatomic fluids are studied using molecular simulation and theory. The overall goal of this study was to develop a theory to predict the properties of fluid mixtures with intermolecular ...
• Predictive Parallelization: A Framework for Reducing Tail Latencies of Web Search Queries ﻿

(2014-04-25)
We have become dependent on web search in our everyday lives. Web search services aim to provide fast responses to user queries, making the tail latency more important to reduce than the average latency. With modern multicore ...
• Prefetching and buffer management for parallel I/O systems ﻿

(2000)
In parallel I/O systems the I/O buffer can be used to improve I/O parallelism by improving I/O latency by caching blocks to avoid repeated disk accesses for the same block, and also by buffering prefetched blocks and making ...
• PREPARATION OF A NEW CYCLOPROPARENE SYNTHON, 1-BROMO-2-CHLOROCYCLOPROPENE, AND STUDIES ON THE SYNTHESIS AND PROPERTIES OF BICYCLO(4.1.0)HEPT-1,6-ENE AND BICYCLO(4.1.0)HEPT-1,7-ENE ﻿

(1986)
1-Bromo-2-chlorocyclopropene (BCC) was prepared by treating 1-bromo-2,2-dichlorocyclopropyltrimethylsilane with tetrabutylam- monium fluoride in tetrahydrofuran at -20(DEGREES)C. Diels-Alder reactions of BCC with 1,3-dienes ...
• Preparation of iodine SWNTs and iodine US-tubes: Synthesis and spectroscopic characterization of iodine-loaded SWNTs for computed-tomography molecular imaging ﻿
